Russian airstrikes on a rural swath of northwestern Syria killed at least seven people, including four children, on Friday, a war watchdog group and rescue workers said, after months of relative calm in the region.
Four aircraft strikes identified as Russian by ground observers have hit rural Idlib, the last rebel-held area in war-torn Syria, according to the Syrian Observatory for Human Rights, which monitors war events such as operations and casualties.
The four children who were killed were siblings, the Britain-based group said.
The White Helmets rescue group gave the same figures and said another dozen people, including eight children, were injured in the strikes.
Russia has been carrying out airstrikes in Syria since 2015, helping its ally President Bashar al-Assad retake territory from rebels and extremist groups.
Strikes have become increasingly rare in recent months, the war watchdog group said.
